Working Principle of electric rail turntable The principle of the electric rail turntable is to rotate the gear by the motor to achieve the rotation of the turntable. When the flat car is completely running on the turntable, the turntable starts to rotate to the desired angle and the connect with the ground rails completely, then the flat car can starts again and runs along the rails. Advantages of electric rail turntable A very common device in the rail transportation system; We can design the capacity, rotation degree as requirement; Adopts electric drive mode and frequency control; Positioning safety requirements are high, there are mechanical and electrical two control methods for braking;
